I have the 52.0 remote and last year the tech talked me into the 50.0 remote that is voice automated. Yesterday every control on the 52.0 works except the mute, volume, and tv on/off button. My 2 year contract is almost up so I thought maybe it could be the remote. I pulled out the 50.0 that the tech set up but we never use and it was doing the same thing. My regular tv remote will do all these things so it is not my tv. I've located the remote to make sure I was using the right one, I've checked the settings, I've changed the batteries, I've unplugged it and replugged it in again, and I did the system info button which showed everything to be good. Since it is both hopper remotes does anyone have any other ideas? Yes I can use my tv remote but it's the convenience of one remote.
